To understand a crypto wallet, we must first understand what cryptocurrency is. In a layman's language, cryptocurrency is digital money. This means transactions occur on the internet; there is no physical platform.

Today most people are opting to invest in crypto despite their high risks. This is primarily due to their extremely high profits. Crypto enables diversification, fees avoidance, transparency, reduction in transaction costs, etc. It certainly has myriads of benefits that outweigh its cons.

Definition of a Crypto Wallet

You must also invest in a quality crypto wallet when you invest in cryptocurrency. What is a crypto wallet? A cryptocurrency wallet functions like your dollar wallet.

It is a software program or physical medium that allows you to store your digital assets. Other than storing, the wallet allows you to sign smart contracts too. Thanks to the signing keys.

Private and Public Keys

The crypto wallet doesn't store the cryptocurrency itself. It stores the public or private keys instead. These keys often act as a pair that enables you to send and receive crypto. In turn, the need for some form of the regulatory body is eliminated.

The public keys are derived from the private keys. They allow you to receive cryptocurrency transactions since they act more like an address that you can share publicly. The private keys, on the other hand, can’t be derived from the public keys.

This is because the private keys prove you are the owner of the crypto. Their primary function is to enable you to access crypto transactions by facilitating encryption and decryption.

The private keys come in various comprehensive forms. They can be a mnemonic phrase or a 64 digit hexadecimal code. Whatever the form, it is vital not to share these keys. Otherwise, you will lose ownership of your crypto.

Private keys are stored in a non-custodial or custodial wallet. Having these keys in a non-custodial wallet allows you to manage your crypto. On the other end, the custodial wallet manages your crypto.
